A 122-year-old dairy equipment company has used Linux to control a robotic cow-milking system (the system is robotic, not the cows). Delaval's “Voluntary Milking System” (VMS) lets the cows decide for themselves when to be milked, and gives dairy farmers a more independent lifestyle, free from regular… milkings, the company says.

The system runs a 2.4.18 Linux kernel on an x86 single-board computer. Be sure to catch the cool videos showing cows using the VMS to milk themselves.
